TERMINAL BOX.

To all. whom it may concern:

Be it known that I, CHESTER C. OBERLY,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illmois, have invented certain new and useful Improvements in Terminal Boxes, of which the following is a specification.

For train lighting purposes it is not uncommon to suspend the axle-driven generator from the truck, in which case the generator swings withthe truck and thus maintains undistorted the driving connection between the axle and generator when rounding curves and in similar circumstances. The wires leading from the swinging generator to the lighting system of the car must, to allow for the shifting of the position of the generator, include considerable slack and heretofore difficulty has been encountered in providing the necessary slack in the lead wires and yet guard against the wires hanging so low as to be subjectjo danger of contact or engagement with the roadbed, switches, etc.

To protect these lead wires from becoming damaged by flying ballast or the-like it has been usual to house the same in canvas or rubber between the points of emergence from the terminal box of the generator and entrance to the car. It has been found that the housings of this character are soon cut to pieces by flying particles and rendered inefiicient without frequent renewal.

It is the object of the present invention to so fashion the terminal box as to take the leads from the top thereof, thus obtaining with the same slack several inches more clearance between the leads and the top of the rails and also obtaining a better disposition of the leads within the box for connection to the several terminals. A further object of the invention is to so construct the terminal box as to provide its outlet with internal threads for engagement with the spiral covering of a flexible armored hose, thus enablin the use of an armored hose housing for t e leads instead of the old canvas tube.

In order that the invention and the man ner of its application maybe readily understood a preferred embodiment of the same is set forth in the following detailed description and in the accompanying drawing upon which such description is predicated. It will be obvious that the invention is sus- Speciflcatlon 01 Letters Patent.

'ceptible of embodiment in other and varied constructions, wherefore'the drawing and description are to be'taken in an illustrative rather than in an unnecessarily limiting sense. In the drawing Figure 1 is a perspective view showing an axle hung generator and the connection with the car system;

Fi 2 is a vertical section through the terminal box; and

Fig. 3 is an elevation of the terminal box with the cover plate removed.

The terminal box is indicated at 11 provided with a removable cover plate 12 and attached to the generator 13 which is driven by the belt 14 from the car axle and supported upon the rods 1515 forming a art of the truck construction. The car bo y is indicated at 16, the conductors to the train system at 17 and the connector box at 18.

A plurality of leads 19 leading from the terminals 20 within the terminal box 11 to suitable connections in the connector box 18 I are of such length as to provide considerable intermediate slack and are housed within the armored hose 21.

- Heretofore it has been usual to takethe leads off from the terminal box at. the bottom or the sides but I prefer to make the connections at-the to of the terminal box in vorder to provide or ample slack in the leads and at the same time avoid having the same de end too low below the car body. To accompllsh this purpose and at the same time obtain an advantageous disposition of the leads within the terminal box the box is provided with a goose neck outlet 22 extending from the top upwardly and laterally and terminating in an opening which is interiorly screw threaded at 23 for engagement with the spiral metallic armor of the hose 21. Itwill be observed that this goose neck has inwardl flarin outwardly converging walls where y the inner terminal portions of the leads are permitted to diverge fan like to theirconnections with the posts 24, whereby the leads are not cramped in any way at the point of connec-' tion with the terminal, the flaring gooseneck constituting in 'efiect an upper continution of the box itself. For greater security the ends of the armored housing may be locked within the threaded outlet of the terminal 'box by means of the set screw 25.

I claim:

1. The combination with an axle-hung generator, and a car lightin system supplied thereby, of atermmal ox having an upwardly and laterally rojectmg goose neck outlet, the goose nec havin flaring walls conver ing from the termina s within the box to t e outlet, and leads extending with slack from the terminals to the car system.

2. The combination with an axle-hung generator, and a car lighting system supplied thereby, of a terminal box on the generator having an upwardly and laterall rojecting goose neck outlet, the goose nee ing flattened in cross section and having flaring walls converging from the terminals within the-box to the outlet, and leads extending from the terminals to the car system.

3. The combination with an-axle hung generator, and a car 1i hting system supplied thereby, of a terminal box having an upwardly and laterally projecting goose neck outlet, with a threaded terminus, the goose neck being flattened in cross section terminus, slack leads extendin and having flaring walls converging from the terminals within the box to the outlet from the terminals to the car system, an a spirally armored lead-housing threaded in engagement with the goose neck terminus.

4. The combination with an axle-hung generator, and a car lighting system supplied thereby including a junction box, of a terminal box having an n wardly and laterally projecting goose nee outlet, with an interiorly threa e terminus, the goose neck being flattened in cross section and having flaring walls converging from the terminals within the box to the outlet terminus, a plurality of leads extending from the terminals to the junction box of the car system, and a spirally armored lead-housi threaded in engagement with the goose nee terminus.

Intestimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
